TYPE-COMPOSING MACHINE.

, Application filed April :4, 1927. semi No..180,698.

It is theprincipal objectof my invention to provide for a composing machine of the type disclosed in myQUnited States Letters Patent No. 1,607,110, granted. November 16th, 1926, a type receiving drum or flat chase which will be so indexed asto be properly located at all times, irrespective of any errors in it. This is accomplished by my improved means for indexing the drum or flat chaseat its ty e receiving end. i l

. It is another 0 ject of my invention to provide improved means. for locking the type receiving drum on its eccentricshafth Other important and incidental objects will be broughtout in the. following specification and particularly setforth in the sub joined claims. v s.

In the accompanying. drawings ill u strating my invention, Figure l' s a. rear view of i the composing machine, partly in section,

showing the ,chase indexing, and locking .mechanism. Figure; 2is a sectional side view of the same]. Figure .3,is an enlarged sectional view taken througli ithe. indexing and lockinginechanism. Figure a is a cross sectional View taken on the line 4 -4 of Figure 1. AndFigure 5 lStlyPBl'S-Pfitl'filVG view of the trip pawl and associatedparts.

Referring to the accompanying drawings for a detailed description of my invention, the numeral 1 designates chasesupport upon which there mounted casting 2 that carries an ejector housing 3. Mounted I in the latter is a horizontal shaft dthat projects" at one end beyondthe housing to re ceive a sprocketfi. l

One side faceof the ejector housing 3 is formed with a deep T608536 fora crank disc 7 .fast on the outer end of the shaft 4 For the purpose ofrotating the cranl; disc't'. the .sprocl zet 5 is connected by a sprocketichain 8 with a sprocket 9 secured toa clutch member lOwhich is free .to rotate about a chase index shaft 11. (See Figural.) The clutch member 10-is rotated by a sleeve 12 through friction discs not shown .iwithin it. The sleeve 1.2 is in turnrotatcd by an electric motor 13 through a geared mechanism. shown and connection with its armature shaft 14 with- 1n a gear box 15. (See Figure 1.)

Formed on thecra-nk disc 7 is a crank pin 16 that is fitted into hole in the rear end of an ejector arm 17 y of the type ejecting described in my said United States Letters Patent No. 1,607,170, although any, other suitable type ejection mechanism may be employed if desired. By the ejector arm 17 the selected type is e ected upon a chase such as the drum 18.

- See Figures 1 and 2.).

The drum 18 applied to. an eccentric shaft 19 journaled at its rear end in a bronze bearing 20 fitted in. a hole in the casting 2.

The front end ofthis shaft 19-is journaled c in a bearing 21 fitted in a hole in the support 1.

The eccentric portion of the shaft 19 is its middle part. At the front end of the latterthere is freely mounted upon the shaft 19 a drum disc 22 into the center of which .a bushing23his pressed. This bushing,

which ispermitted free rotation upon the shaft .19, has a shoulder 2a which abuts the shoulder formed by the eccentric portion of said shaft. Secured the shaft. 19 in front shaft 19 at the other end of its eccentric portionp This drum 26 is floatingly held upon the shaft19 by a collar 28 secured to the latter. q The lower semi-circular portions of. both drum discs 22 and 26 are filled with lead or other weighty substance to counterrbalance the weight of the chase drum 18 which is easily applied to the eccentric portion of the shaft 19 by the following means.

Upon the top portions of the disc drums 22 and 26; which are flattened to receive a flat chase when one is used, the drum 18 is mounted. Upon the inner surface of the drum 18 are two pairs of ears 29.

ceiving en s ring 47.

Each pair of ears 29, 29 supports a hinge pin 30 for .he supper end of a spring clamp 31. These clamps 31, 31 are formed in U shape at their bottom portions to fit tightly around the eccentric part of the shaft 19, from which they are readily removed by turning the eccentric shaftldil" by means of a handle 32 applied to its front end. Thus the drum 18 may be easily secured to the shaft 19, and removed therefrom withat the necessity of prying it out a screw driver or other instrument. ,(See Figure 2.)

For the purpose of properly locating the drum 18 to receive the selected type from the ejector, thefollowing means are employed. Pivotally mountedon astud 33 secured tothe chase support 1 is" a vertically disposed index pawl operating lever 34 whichcarries on its upper end a fulcrum pin 35. Pivotally' secured at its rear end to this pin 35 is an index pawl 36 formed at its front end with a downwardl. projecting nose 37 adapted to engage at their type rethe conventional T slots 38 formed in the periphery of the drum. (See Figures 1 and2.)

Adapted to slide upon the shaft 11 for the purpose to be hereinafter described, is a drum cam. 39 formed'witli two cani grooves 40 and 41'. Carried by the lower end of the lever 34' is a roller 42 which is received by the groove 40 in said cann (SeeFigure 1.)

The drum cam 39 is rotated fromth'e shaft 11 by a collar 43 pinned to the latter and formed with two axial pins 44, 44 adapted to enter holes in the adjacent face of said cam. (See Figurel.)

For the purpose of rotating the shaft 11 at the time it is desired to index the drum 18, the followin means are provided. Beyond an oil-less bearing 45 in the casting 2, for the, shaft 11, there is pinned to the lattor a clutch spool 46 and an outer clutch (See Figurel.) Formed in the continuously rotating clutch member 10 is an axial hole 48 into which is driven a stud 49 formed with a shoulder 50. (See Figure 1.) Longitudinally slidahle from a groove in the spool 46, to a position in front of the shoulder 50 of the stud 49, is a clutch trip .51 formed with a slot adapted to receive the lower end of a tri pawl 52. )Vhen this trip pawl is raise above the slot by means soon to be described, the clutch trip 51 will be forced in front of the shouldered stud49 by a compression spring 53 located in a'hole. in the outer cl'utch'ring 47.v (See Figure 1.)

\Vheu the clutch trip 51 is thus in a position in front of the shoulder 50 of the stud 49, the clutch member 10 will rotate the shaft 11 until the trip 51 is restoredto its normal position in the slot of the clutch spool 46 by the spring means now to be de scribed.

The pawl 52, which en ages in the slot of the clutch trip 51, is fu crumed on a pin 54 secured to the casting 2. (See Figure 2.) To the rear end of said pawl is connected one end or a tension spriagfia whoseother end is secured by apin 56 to sllid casting. This spring is so tensioned as to hold the nose of thepnwi .52 in nihe lim trip 51 until itis withdraw" l8 theisoienoid means soon '0 h des ribed As shown in Figure 5,'the pawl 52 is formed at its front end with an overhanging shoulder 57 and a downwardly projecting nose 58 which is received by the slot in the clutch trip 51. Just above its nose 58 the pawl 52 is formed with a'beveled cam surface 59 ii is rained on it. After the clutch trip 51' as made one revolution with the rotatin 1 ch-rch'member to to which it is connected its engagement with the stud 49, the thin'eam portion 59 of the pawl 52 will we'd e into the sllit in the clutch trip 51 to sli e it back and away from the stud 49 against the compression of spring 93, until said clutbh' trip hasentirely cleared the stud, whereupon the clutch member 10 will be free to rotate wi'lilimit fturning the shaft 11. n

For the purpose of lifting the nose 58 of the pawl 52 above the slot theciut'ch trip 51 to index the drum 18 one 5 nice or more, Iprovide a conventional a'l solenoid 60 whose inn 1" 61 is adapted to en ge the shoul er 5 on the pawl. There re, when the solenoid 6G is energized through means connected with a ewrijter k'e' hoard (not shown), the will raised intoengagem'ent wi the shoulder 57 on the pawl 52 to lift its nose 58 above the slot in t be forced in front of the" stud 4.!) b the spring 53, to connect the clutch men'ilier 10 with the shaft 11 The lather will thenjturn the cam drum 39 to actuate the. lever" 34 which will cause the index pawl 36 to turn the drum one space for every revolution of the shaft 11. Since the engagement of the projection 37 on said pawl 36 is at the t 'y e receiving end' of the drum 18, the latter will be properly indexed at all times to receive the ejected type, irrespective of'any irre" larities inlthe rnachining'of the drum, or at chase plate where one is emplo d. V

For the purpose of llftingt e projection 37 of the indexing pawl 36out'of'theT slot 38 which it has engaged to clear the latter when said pawl is moved rearwardly by the lever 34, the following means arep'rovided. Secured to the pin 35 isthe front end of a spring lever 62 which at its're'arend carries a pin 63'that is fitted in aslbt 64 in than per end'ofalink 65; The'latt r ispivntall;

e trip 51, whereupon the latter will tached to the shaft 11 beyond a bearing 71 for the latter secured to the support 1. The drum cam is so timed that it will actuate the bell crank 66 tolift the projection 37 on the pawl 36 out of a T slot 38 just prior to the I rearward movement of said pawl. I By means of a torsion spring 72 surroundingthepin 35, pressure is exerted by one end of said spring upon the pawl 36 to force its projection 37 into the next T slot 38 before the forward movement of the; le-. ver 34. (See Figure 4..) I

For the purpose of locating the drum 18 in its proper relation to the type ejector and for locking the drum in its indexed position, Ihave provided alocat-ing pawl 7 2 having a projection 7 3 adapted to engage the T slot 38 near the type receiving end of the next slot. This locating pawl 72Pis fulcrumed on a shaft74 journaled in a casting 7 5 secured to the support 1. (See Figures 1 and 5.) I j Also secured to the shaft .74 is a spring lever 76 on the .upperportion of which there is a projeetionfi? to whicha flat spring 78 is attached. At its ,lower curvedend the spring 78 is adapted to engage a projection 79 on a locating-pawl operating-lever 80 which, is loosely mounted at its upper end on the shaft 74.. Formed on the lever 80 opposite the projection 79 is a similar projection 81 adapted to. be engaged the lower end of the spring lever 76.x (See Figure 1.) 1 I i 1 The lower end of the lever 86 carriesa roller 82 which travels in the groove 41 in the drum cam 39. The groove 41 is so timed that it will actuate the lever 80 andspring lever 76 to engage theprojection 73 on the pawl 7 2 in a T slot 38 immediately after the drum has been indexed by the pawl 36, to hold the drum in proper relationto the type ejector; 1 y

hen the drum 18 isto be indexed by the pawl 36, the locating pawl 72;.is lifted out ofits T slot 38 by the drum cam 39 and connected levers 80 and 76. f I

The speed of the motor-driven clutch member 10 may be regulated througlrthe following brake mechanism. Referring to Figures 1 and 2, the numeral 83 designates a brake band 84 which surrounds the clutch me1nbe1m10 and whichis anchored to a stud 8d secured to the chase support 1. wThis band may be tightened or released to retard or quicken the 'speedof the clutch member 10, by means of a screw 85 which passes through the free ends of the band. On one end ofthis screw is a nut 86 and surrounding its other end aspring 87.

from said ejector,

-.ejector, a slotted chase for receivin i In order to facilitate the removal of the drum 18, or a flat chaseifemployed, the pawls36 and .72 may be lifted above the chase by moving the drum cam 39 along the shaft lltoward thelcamdriver43. For the purpose of shifting the drum cam 39 along the shaft, said cam isformed at its rear end with a cam groove 88 that receives roller 89. carried by a crank 90 on a shaft 91 which may be rotated by. any suitable manual means, such as a, l1andl.e.92.
